  • Notes

  • This is a signal generator that covers approximately 93 kHz to 31 MHz in 10 bands.  (There was a slight variation in coverage due to a production change.)

    The attenuator gives an output of from about 1.2 volts down to 0.5 μV.

    Judging by the component layout diagram, the case used was the same as for the 14R7490.

    This was a high end instrument that would have been used by the military mainly.
